The research study dwells to the goal of producing a viable sustainable building material that utilizes a procedure of aerated concrete or foaMinerva C. Roselete through substituting and reducing the amount of conventional construction materials with agro-waste products. These components that were replaced and reduced by agro-waste were sand aggregates and Portland cement. The sand aggregate was completely replaced by rice hull ash, an agro-waste product produces constantly in the region and is high in silica content, and the Portland cement amount was reduced, with the additional of aggregates that are also agro-waste products, which were coconut husk fiber and banana fiber. The construction product that was develop was for the core of a sandwich wall panel. The researcher formulated four sample types each having varying amounts and combinations of the main components (Portland cement, rice hull ash, coconut husk fiber, banana fiber). The manner of production of such sandwich cores categorizes it as foaMinerva C. Roselete or aerated concrete with the use of an additive of a protein based foaming agent, thus would exhibitlightweight properties. Each set sample type was cured within seven days with a concrete accelerator additive to obtain a testable quality. The samples undergone five test to evaluate the qualities each sample formula has and analytically compare them to each other for the best product with the most optimal performance. The test conducted were compressive strength test, material density, flexural strength test, fire resistance test, and water absorption test. In manufacturing the samples, it was apparent that the moreadditive aggregate the difficulty of the workability increase, this cause the need of more water to be used and thus weaken the strength of samples, this was most observable to ARHC 4 having two unique additives in the mix (coconut husk fiber and banana fiber) having the lowest strength of about 706 PSI. The density of each sample was qualifiable for lightweight concrete standard (1.84 g/cm3 density of lightweight concrete materials specified by the ACI 318 – 14) with the samples having density of about 1.49734 g/cm3, this was due to the agro-waste aggregates being lesser dense and for the foaming agent mixed. Though the foaming agent wasn’t consistent with its distribution throughout the inside of the samples, each samples having concentrated spots of high counts of micro bubbles compared to other location. Flexural strength of each set samples varies, and was apparent that more agro-waste aggregates have a higher bending stress performance with ARHC 3 and 4 leading the charts with average strengths of 514. 675 psi and 524. 77 psi, respectively. Each sample was able to withstand direct fire up to four hours of exposure without getting engulf in flames, with only minor burn marks as residues. The water absorption performance of each sample was at the lower end of the spectrum with the lowest absorption rate of 2.4% for ARHC 1 and the highest having 8.32% for the ARHC 2. The final sample product to be chosen was the ARHC 3 the composite concrete material with banana fiber, for its balance overall performance in all test conducted.
